The closing member of a globe valve is a plug-shaped valve disc with a flat or conical sealing surface. The valve disc moves in a straight line along the centerline of the valve seat. The valve stem can be of a lifting-rotating type, suitable for controlling the flow of various types of fluids, including air, water, steam, corrosive media, slurry, oil, liquid metal, and radioactive media. Therefore, this type of shut-off valve is highly suitable for use as a cutoff, regulating, or throttling valve.
